Review of IAEA specialists' meeting on irradiation embrittlement, thermal annealing and surveillance of reactor vessels, Vienna, Austria, 26-28 February 1979

The basic theme of the meeting was the exposition of knowledge which will permit the evaluation or projection of the reactor pressure vessel condition after neutron irradiation so as to assure vessel integrity for the reactor's economic life. This applies to both current and future light water reactor (LWR) systems. With this basis, the participants, organizers, authors, and discussors freely provided the latest available information as well as ideas for added research and development to meet the theme goal. Papers from Belgium, Czechoslovakia, France, the Federal Republic of Germany, India, Japan, The Netherlands, Sweden, the United Kingdom, and the United States covered various topics within the framework of studies on irradiation embrittlement, surveillance, and thermal annealing to correct radiation damage. The collective result in the long run would be to provide the basic data on which to base criteria for assurance of LWR vessel integrity
